City Chemical manufactures high purity Silver Cyanide, CAS 506-64-9 in bulk quantity. Silver Cyanide is an off-white powder insoluble in water commonly used for research and as an ingredient in silver plating. Cyanide is an optimal complexing agent - which increase the solubility of metal salts - because of its ease to chemically manipulate and elegant white color it yields. When a metal with lower electrode potential is added to silver cyanide, silver ions displace the metal's atoms and provide a strong adhesion to the coating.
